摘要： A projection exposure apparatus can correct focal point movement caused by an environmental change, such as a change in temperature or atmospheric pressure, during an operation, while minimizing occurrence of a new aberration such as a spherical aberration caused by focus correction. The projection exposure apparatus of this invention exposes a mask pattern on a photosensitive substrate via a projection optical system. The projection optical system includes a refraction or reflection type optical member, and a diffraction type correction optical member. The correction optical member has focal position movement with an environmental change during an operation in a direction opposite to the direction of focal position movement of the optical member with the environmental change during the operation.

摘要： A method of manufacturing an exposure apparatus includes a step of providing a projection optical system that projects a pattern image formed on a mask onto a photosensitive substrate. Additionally, a surface of a correction member having a predetermined thickness is locally tooled or processed in order to correct random aberration that remains in the projection optical system. The tooled correction member is arranged between the mask and the substrate, irrespective of the mask. Furthermore, when the projection optical system is provided, an aberration caused due to the predetermined thickness of the correction member is taken into account in advance.
